  • This paper summarizes the presentations and discussion at the Energy Options for the Future meeting held at the Naval Research Laboratory in March of 2004. The presentations covered the present status and future potential for coal, oil, natural gas, nuclear, wind, solar, geothermal, and biomass energy sources and the effect of measures for energy conservation. The longevity of current major energy sources, means for resolving or mitigating environmental issues, and the role to be played by yet to be deployed sources, like fusion, were major topics of presentation and discussion....

  • Energy management and conservation are the keys to using fuel and electrical energy in the most efficient way. Proper energy management can lead to big savings on the operating costs of a building. If fuel and electrical energy consumption are reduced, money will be saved as a result. Many residential, industrial, and commercial buildings have already undergone changes that have resulted in the savings of both energy and money. Any building can be made more energy efficient when proper energy management procedures are applied....

  • In the year 2000 energy again made the headlines. Energy management programs that became dormant were revitalized. Companies again became aware that the energy problems of the 1970s, 1980s and 1990s did not go away. The California “power crisis” indeed could spread to other states and not only impact a company’s profitability but could also put many out of business. The first edition of Plant Engineers and Managers Guide was written in 1977 and it was the first book to address the need for industrial energy management....

  • The rate of energy conversion or transmission (i.e. power) is related to the physical quantities such as force, speed, voltage, current, etc.For mechanical system, rate of energy transfer (i.e., power) to an object is the product of the force (F in Newton) and the speed (S in meter/sec) of the point where the force is applied.Q1. A person pushes an out-of-gas car with a force of 100 Newton (about 22.5 lb of force) to maintain a speed of 0.2 m/s. It took him 10 minutes to get to the nearest gas station. How much energy did this person use to do this work?...

  • This Notice provides guidance concerning qualified energy conservation bonds under § 54D of the Internal Revenue Code (Qualified Energy Conservation Bonds). This Notice addresses questions regarding qualified conservation purposes eligible for financing with these bonds, particularly (1) how to measure reductions of energy consumption in publicly-owned buildings by at least 20 percent under § 54D(f)(1)(A)(i) and (2) what constitutes a “green community program” under § 54D(f)(1)(A)(ii).

  • In January 1976, the Transportation Energy Conservation (TEC) Division of the Energy Research and Development Administration contracted with Oak Ridge National Laboratory (ORNL) to prepare a Transportation Energy Conservation Data Book to be used by TEC staff in their evaluation of current and proposed conservation strategies. The major purposes of the Data Book were to draw together, under one cover, transportation data from diverse sources, to resolve data conflicts and inconsistencies, and to produce a comprehensive document.

  • THE PETROLEUM AND NATURAL GAS CONSERVATION BOARD Was created in 1938. Its responsibilities have since been expanded to all types of energy resources, and it is now known as the Energy Resources Conservation Board (ERCB). The occasion of the organization's fiftieth anniversary caused many of us to think about the significant role that the Board has played in the development of the province's energy industry.

  • This book is a comprehensi ve and illustrated work on high temperature air combustion (here called HiTAC), which has revolutionized our paradigm on the use of all kinds of fossil, alternative, waste, and derived fuels for energy conversion and energy utilization in industry. Significant experimental knowledge and insights from many practical devices have resulted in the utilization of HiTAC technology for many applications. The traditional definition of flame is that which gives heat and light during chemical reaction between reactants.

  • Few issues display more clearly the competition between China’s drive to become economically developed and to conserve biodiversity than hydropower development. This is the subject of China’s most recent environmental controversy. In August 2003, the National Development and Reform Commission, a powerful economics super-ministry, authorized construction of a 13-station dam along the Nu1 River (Nujiang) in Yunnan Province. After at least a decade of construction, the dam would become the world’s largest.

  • In July of 1994, Comet Shoemaker-Levy struck the planet Jupiter, depositing 7 × 1022 joules of energy, and incidentally giving rise to a series of Hollywood movies in which our own planet is threatened by an impact by a comet or asteroid. There is evidence that such an impact caused the extinction of the dinosaurs. Left: Jupiter’s gravitational force on the near side of the comet was greater than on the far side, and this difference in force tore up the comet into a string of fragments.
